Atal Tunnel (Rohtang, on the Manali–Leh route) is a dramatic road-through-the-mountain experience: dark tunnel architecture, misty mountain approaches, and sudden light at the portals. Visit in winter for snow textures or summer for clearer alpine ridges; best light comes early morning or late afternoon when portals glow. Roads can be closed during heavy snowfall.
